Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends. He swears to himself each day that he'll stop, and each day he fails.
This is the key to the seal of hell...
...هذا المفتاح المؤدِّي إلى ختمِ الجحيم
Dies ist der Schlüssel
für das Siegel der Hölle …
Es la llave para romper el sello…
Es la llave para romper el sello…
C’est la clé d’un pouvoir infernal,
Questa è la chiave per il sigillo dell'Inferno...
Esta é a chave do selo do inferno...
Моя повязка — ключ, который запирает ад.
